PLANTATION -- Angry residents, shaken by blasting for construction projects, have prompted Mayor Frank Veltri to hire a professional seismologist and request a revision of county standards.

Veltri said he has received 150 phone calls from residents complaining that continuous dynamiting along Northwest 136th Avenue has collapsed wells and cracked walls.

Nicole Stevens, a Lago West resident, called the mayor after a particularly alarming Friday morning blast.

``The tremor was so strong it set off the alarm of a car in front of my house,`` Stevens said. ``We have a terrible feeling that the floor is going to split.``

But reports from the county and two seismology companies have determined the activity falls within current county noise and vibration standards.

The information led Veltri to hire a seismologist not affiliated with the development firms now blasting near the Lago West and Lago Mar communities.

``It certainly is wrong if there are houses being damaged,`` Veltri said. ``We`re going to make sure (blasting is) within the present tolerances and then do something to reduce the tolerances.``

Veltri said he plans to send a letter to the county requesting a revision of current standards.

But council member Larry Freilich said sending a letter may be futile.

``I doubt the county would revise their standards for this case alone,`` Freilich said. ``The standards do not take into account the people who live in the area and how it cracks their walls.``

Those who live near the blasting project have agreed.

``Even if it is below the limit, the blasting is bothering us,`` said Attila Kocsardy, a resident of Lago West. ``I have cracks on my walls. It`s so scary, I`m afraid the house is going to collapse. It`s so scary and no one seems to care.``
